A 8' Claims. =l This invention relatesto a" loom .and ,moreYparticularly to a control forstopping'the loom. 'Itis usual vin theoperation of haloorn which lis auto- K4rnatically causedto'stop 'whenthe lling 'fails that the 'shuttle will come to rest at the transfer'end-of "the lay rather than atth'e end of "thelay vwhere the shipperllever with 'its handle is located. When the shuttleofa loom comes torest at the Iend of the lay remote 4from 'thatfend'at which the shipperhandle is located,itibecomesnecessary 'for the loom operator to turnover the crank shaft Yloy hand and move the shuttle rfrom the transferend of 'the lay Ito the vshipper handle end ofthe lay Vto piece up 'therfilling. A loom operator who ldoesfturn over nthe crank shaft "forvthis purpose lusually 'getsh-is handsdirty and the `woven fabric orthread will in 'many instances 4thus become soiled from the v4operatorslfhands, `besides sometime i-s lconsumed inthe turning over the loom forsuch lpiecing up.

One -of the 'objects'of `this invention lis jto "so delay the movementof the shipper handle in Vvits -travel v`from operating position 'toinoperating "position `that-.the shuttle Awill takefone more pick andwill cornefto rest 1at the shipper handle enol -of the lay.

:Another-object -of 'this 'invention "is -to provide .a veryzsimpleattachmentto the alreadyexlsting loom `-vvliic'h may l'be simplyassembled thereon '-to .cause ythel desired action.

.A more kspecificobject of 'this 'invention -isfto 'l -fprovide a hookwhich @will ycatch the shipper -handle whensrelease'd from its operatingposition( ato retainltheshipper handleuritil'thefllling motion has'returned from aposition which causes .release .of .theshipper hand-1e.

With'` these :and-other'zobjects in views` thei'nven- .tion consists of.certain novel fea'tures of con- :structionsas Vwill ibezfmore rfully.describedran'd particularly Ypointed Vzout in fthe A#appended claims.

Fig. asectional view .showing the shipper lever and ...springfonmovingit to one fend for the .slot .in which .it operates.

In .proceeding Awith this invention, I attach a catch on the :releaseVor shipper motion lever which pushes theshipp'er "handle or lever fromits voperating"position into a *position to 'stop the loom,whlchfcatc'h'will engagethe shipper lever and hold it 'fromtinoving .toinoperative position, and I also :provide a spring which, after thefilling fork slide has returned from Aactuating positionywill cause therelease lever to release the shipper lever by retracting "thehook fromengagement therewith. This retarding 0f the stopping of the loom will beso-tirn'ed as to cause the shuttle vto :moveto the 'shipper hand-le `endof the lay, making "it unnecessary to "turn over the crank shaft 'byhand and manually move the shuttle across -the lay.

With reference tothe drawings, l0 designates a part of the frameworkl'oftheloorn and I-l vthe cam shaft having va cam I4 thereonwhich-'engages the cam follower I5 secured at the end of the-camfollower lever |56 which 'is `pivoted as at l1 (see Fig. 3) and hasafollower dog lsecured on the other side of its pivot whichvos'cillates'each time the cam shaft rotates. This ydog -has'th'ecamffollower trip I9 secured thereon as well as a filling motion hook20. The filling forkZ'l is mounted in its holder 22 'and pivote'd as -at2-3 and 'has a latch 24 to 'engage the catch 25 of 'the filling Inotionhook 20 in case the lling 2B, which Ais shown as spaced from the lay(Fig. 1) designated generally 21, fails or is not prescritto swing thetrip 2| out of the way. 'The 'filling fork slide designated 'generallyY21has *mounted on it the Vlll'lng motion trip 28, and this slidewillmove forwardly on the lling motion stand 29 so that fthe trip '23will engage the filling motion finger 30 on the end of the shipperrirno'tion lever 31, 'which is pivoted as at 38,'to swing the arm 39 ofthe release lever 31 into engagement with theshipp'er lever 40 "having'a handle y35 vat the upper 'end 'thereof A(See Fig. 4).

. This 'shipper leverl's 'shown -as located in the slot 4| in theshipper f1ock42 4which/has `an oiset or notch `43 along one Wall 44 ofthe slot 4l so as to .provide a Yshoulder 45 with which the lever 31which contacts the shipper lever 40. This hook is provided with anabutment surface l to engage the edge 52 of the shipper lever 4G andhold the same while in engagement therewith. This surface 5l is sopositioned on the arm 39 that, when the shipper lever is in operatingposition, the surface will be spaced from the shoulder 45 in thedirection of the inoperative end 46 of the slot 4l.

When the conditions are such that the lever 3l will be swung clockwisearound its pivot 38 by movement of the filling fork slide, the end ofthe arm 39 will push the shipper lever out of the notch 43 and beyondthe shoulder 45. The shipper lever will then start to move toward theinoperative end 46 of the slot 4i by a constantly acting tension spring36 usual in mechanisms of this character with the shipper lever slidingalong the Wall 44 of the slot. However, before the shipper lever hasmoved any substantial amount, the surface 5l of the catch 5G will engagethe shipper lever and arrest its movement, Thus, the shipper lever doesnot move far enough to canse stopping of the loom, and the shuttle 55which has travelled to the transfer end of the loom will be returned bythe picker stick at the transfer end of the loom into the shuttle box 5Eas shown in Fig. 1, However, the spring 5l', as shown in Figs. .1 and 2,is

acting upon the filling fork slide to return the slide; and after theslide is returned, the spring 41, acting upon the releasing lever 31,will swing this lever counter-clockwise to Withdraw the catch or hook 50from the shipper lever 40, which being .against the wall 44, as shown inFig. 2, is then free to be moved by its spring along the Wall 44 to theinoperative -end 46 of the slot 4! and the loom will be stopped.

By this arrangement, the delay in the movement ofthe shipper handle toan inoperative position Yby catching the same and holding the same untilthe lling fork slide has returned permits just suicient time for thepicker stick at the opposite end of the loom to operate and cause theshuttle to be returned to the end of the loom where the shipper lever islocated.

It will be apparent that the shipper lever is provided with the usualhandle for operation which extends upwardly and is enlarged somewhatfrom the lever portion thereof which is out olf in the showing in thedrawing so as not to hide the edge of the lever which catches on theabutment and the action with hook 59 which would otherwise be hidden.
